DOOR-CHECK.

SPECIFICATION forming part of Letters Patent No. 349,604, dated September 21, 1886.

Application filed May 23, 1885.

To all whmn it may concern.-

Be it known that I, GEORGE XVAsHTNeToN RANDALL, of Boston, in the county of Suffolk, of the-Commonwealth ofll'lassachusetts, have invented a new and useful. Improvement in Door-Holders; and I do hereby declare the same to be described in the following specification, and represented in the accompanying drawings, of which Figure 1 is a front elevation of a door-frame and door with my invention applied to the latter. Fig. 2i-s a front view, Fig. 3 a side elevation, and Fig. 4 a Vertical and longitudinal section, of the door-holder, such figures being on an enlarged scale with reference to that of Fig. 1.

The nature ofmy invention is duly defined in the claim hereinafter presented.

In such drawings, A denotes a tube provided with four cars, a, extending from it laterally, and'being for fastening it to the front face of a door, B, by means of headed screws going through such ears and screwed into the door.

In the front of the tube or case A there is a long slot, 1), which opens through the upper end of the tube or case, and has one edge serrated, or formed with a range of teeth, as shown at c. Extending lengthwise through the said tube is a spindle or rod, C, provided at its lower end with a foot, (I, having rubber or leather or other suitable frictional bottommg, e.

\Vithin the case and on the rod is a shoulder, f, and resting on the shoulder and encompassing the rod is a spiral spring, D, above and on which is a tube or sleeve, E, that is concentric with and to slide on the rod. lVhen in its highest position, the tube E butts against a head or shoulder, h, fixed or screwed on the rod at its top.

, A handle, 1', extends from the tube E at its upper end, such tube at its lower end being provided with a tooth, k, projecting from it, and triangular in its transverse section. This tooth is to engage with the serrations of the 'slot b, the said slot being wide enough to allow of the tooth being turned into orout of engagement with such serrations.

In Fig. 1 the door is shown at B, its frame Serial No. 106,426. (No model.)

at F,and the door-holder at H, there being at and projecting from and secured to the lower part of the door a bracketor guide, I, for the rod to slide through.

After having opened the door to any desired extent the handled is to be forced downward, so as to cause the foot d to restupon the floor, after which the handle is to be pressed farther downward to cause the sleeve E to compress the spiral spring to the necessary degree. The handle should next be moved so as to turn the sleeve laterally and cause its tooth to engage with the rack or series of teeth of the slot 1). The spring will then press the rod 0 downward to cause its foot to bear with sufficient friction 011 the fioor'to hold the door open.

At the upper end of theslot b, and leading laterally out of it, is a notch, Z,which, formed in the tube A, serves to receive the tooth, in order to keep the rod raised out of contact with the fioor when such may be desirable.

This door-holder is very efficient in practice.

me as occasion may requirethat is to say, there are to the rod and spring and their supportingtube the sleeve E and its tooth and the toothed slot inv the tube A. Nor do I claim a door-checksuch as shown in United States Patent No. 155,158-in which the vertical slide carrying a curved arm having the roller is not revoluble in the case, and the slide that carries the spring-case is revoluble, but is susceptible of vertical movements only, like the slide.

I claim- The door-holder consisting of the guidetube A, slotted, and having serrations in one I do not claim a door-check constructed as with means of increasing the downward pressside and a notch at the top of the slot, the cylindrical rod 0, having the shoulders f and h; anclthe frictional foot (1, the sleeve E, provided with the handle 6 and tooth 7c, and

adapted to slide lengthwise and turn 1aterally on the upper part of the rod 0, and in the gnide-tube-A, and the spring 1), around the rod between the sleeve and the shoulder f, as set forth. I
